黑龙江省节能日光温室冬季光温特点的研究

Study on Winter Light-Temperature Characters of Sunlight Energy-Saving Greenhouse in Heilongjiang Province

通过对哈尔滨地区东农 98- 、98- 型节能日光温室冬季光温的系统观测 ,选择有关的光温指标对节能温室的光温分布进行了系统对比分析 ,指出了东农 98- 、98- 型日光节能温室在增光和增温效应上是很显著的 ,它能高效地利用高纬地区冬季的光温资源。进一步指出了提高日光节能温室增温效应所应攻克的难题 ,为 4 4°N以北的高寒地区冬季蔬菜生产安排提供了科学的依据。

The systematic observation on winter light-temperature characters of 98-Ⅰ and 98-Ⅱ sunlight energy-saving greenhouse in Harbin region. The correlated light-temperature indexes were selected and the light-temperature distribution in energy-saving greenhouse were comparatively analyzed. Resuts indicated that the elevated light-temperature effect of 98-Ⅰand 98-Ⅱis very distinct. It can efficiently utilize light-temperature resources in area of high latitudes in winter. In addition, more work should be done to solve the problems in improving temperature effect in sunlight energy-saving greenhouse, providing scientific basis for vegetables production in winter in 44°N north latitude cold zone.
